AP Physics C: Mechanics
4.2 Change in Momentum and Impulse
4.1 Linear Momentum
A tennis ball of mass \(0.060\text{ kg}\) travels horizontally toward a racket at a speed of \(25\text{ m/s}\). After being struck by the racket, the ball travels horizontally in the opposite direction at a speed of \(35\text{ m/s}\). If the ball remains in contact with the racket for \(4.0\text{ ms}\), what is the magnitude of the average net force exerted on the ball during the collision?
